Awiri omwe amapanga antimony trioxide padziko lonse lapansi asiya kupanga. Ogwira ntchito m'mafakitale adasanthula kuti kuyimitsidwa kwakupanga ndi opanga awiriwa kudzakhudza mwachindunji msika wa antimony trioxide. Monga gulu lodziwika bwino la antimony oxide kupanga ndi kutumiza kunja ku China, UrbanMines Tech. Co., Ltd. amapereka chidwi chapadera ku chidziwitso chamakampani apadziko lonse lapansi cha zinthu za antimony oxide.
Ndi chiyani kwenikweni antimony oxide? Kodi pali mgwirizano wotani pakati pa ntchito zake zazikulu ndi ntchito zopanga mafakitale? Pali zina zomwe zapezedwa m'munsimu kuchokera ku gulu la Technology Research and Development Department of UrbanMines Tech. Co., Ltd.
Antimony oxidendi mankhwala zikuchokera, amene lagawidwa mitundu iwiri: antimoni trioxide Sb2O3 ndi antimoni pentoxide Sb2O5. Antimony trioxide ndi white cubic crystal, sungunuka mu hydrochloric acid ndi tartaric acid, osasungunuka m'madzi ndi acetic acid. Antimony pentoxide ndi ufa wonyezimira wachikasu, wosasungunuka m'madzi, wosungunuka pang'ono mu alkali, ndipo ukhoza kupanga antimonate.
Kodi zinthu ziwirizi zili ndi ntchito yotani m’moyo?
Choyamba, amatha kugwiritsidwa ntchito ngati zokutira zotchingira moto komanso zoletsa moto. Antimony trioxide imatha kuzimitsa malawi, motero imagwiritsidwa ntchito ngati zokutira zotchingira moto m'moyo watsiku ndi tsiku. Kachiwiri, antimony trioxide imagwiritsidwa ntchito ngati retardant lawi kuyambira zaka zoyambirira. Kumayambiriro kwa kuyaka, kumasungunuka pamaso pa zinthu zina, ndiyeno filimu yotetezera imapangidwa pamwamba pa zinthuzo kuti ilekanitse mpweya. Pa kutentha kwambiri, antimony trioxide imapangidwa ndi mpweya ndipo mpweya wa okosijeni umachepetsedwa. Antimony trioxide imathandizira kuchedwa kwamoto.
Onseantimony trioxidendiantimoni pentoxidendi zowonjezera lawi retardants, kotero kuti flame retardant zotsatira ndi zoipa pamene ntchito yekha, ndipo mlingo ayenera kukhala lalikulu. Nthawi zambiri amagwiritsidwa ntchito limodzi ndi zoletsa moto ndi zopopera utsi. Antimony trioxide nthawi zambiri amagwiritsidwa ntchito limodzi ndi halogen-containing Organic substances. Antimony pentoxide nthawi zambiri amagwiritsidwa ntchito molumikizana ndi organic chlorine ndi bromine mtundu retardants lawi, ndi synergistic zotsatira akhoza kupangidwa pakati pa zigawo zikuluzikulu, kupanga lawi retardant zotsatira bwino.
Hydrosol ya antimony pentoxide imatha kufalikira mokhazikika komanso mokhazikika mu nsalu slurry, ndipo imamwazikana mkati mwa ulusi ngati tinthu tating'onoting'ono, toyenera kupota ulusi woletsa moto. Itha kugwiritsidwanso ntchito pomaliza nsalu zoletsa moto. Nsalu zomwe zimachitidwa ndi izo zimakhala ndi kuthamanga kwapamwamba, ndipo sizidzakhudza mtundu wa nsalu, choncho zotsatira zake zimakhala zabwino kwambiri.
Maiko otukuka m’mafakitale monga United States anafufuza ndi kutukulacolloidal antimony pentoxideinorganic kumapeto kwa zaka za m'ma 1970. Kuyesera kwatsimikizira kuti kuchedwa kwake kwa malawi ndikokwera kwambiri kuposa kwa non-colloidal antimony pentoxide ndi antimony trioxide. Ndi antimony-based flame retardant. Imodzi mwa mitundu yabwino kwambiri. Ili ndi mawonekedwe a mphamvu yocheperako yopendekera, kukhazikika kwamafuta ambiri, kutulutsa utsi wochepa, zosavuta kuwonjezera, zosavuta kubalalika, komanso mtengo wotsika. Pakalipano, antimony oxide yakhala ikugwiritsidwa ntchito kwambiri ngati choletsa moto m'mapulasitiki, mphira, nsalu, ulusi wamankhwala, zamagetsi ndi mafakitale ena.
Kachiwiri, imagwiritsidwa ntchito ngati pigment ndi utoto. Antimony trioxide ndi inorganic pigment woyera, makamaka ntchito utoto ndi mafakitale ena, popanga mordant, kuphimba wothandizila enamel ndi ceramic mankhwala, whitening wothandizira, etc. Angagwiritsidwe ntchito monga kulekana kwa mankhwala ndi alcohols. Amagwiritsidwanso ntchito popanga ma antimonate, mankhwala a antimoni ndi makampani opanga mankhwala.
Pomaliza, kuwonjezera pa ntchito yoletsa moto, antimony pentoxide hydrosol itha kugwiritsidwanso ntchito ngati mankhwala opangira mapulasitiki ndi zitsulo, zomwe zimatha kulimbitsa kulimba kwachitsulo ndi kukana kuvala, ndikukulitsa kukana kwa dzimbiri.
Mwachidule, antimony trioxide yakhala chinthu chofunikira m'mafakitale ambiri.
